Mechanical Engineering: Liquefaction Process
http://mechanic-info.blogspot.com/2012/08/liquefaction-process.html
Machine element, heat transfer, thermodynamic, fluid mechanic, combustion etc. Liquefied gases are widely used for a variety of purpose, for example as liquefied natural gas in cylinder as a source of domestic fuel in rural areas and as oxygen for rocket and for blast-furnace operation. The essence of all liquefaction process is to cool the gas until it enters the two phase region. This cooling may be accomplished in several ways. 1 Cooling at constant pressure, as in a heat exchanger. The advent of auto...

Mechanical Engineering: Basic Fluid Flow
http://mechanic-info.blogspot.com/2012/05/basic-fluid-flow.html
Machine element, heat transfer, thermodynamic, fluid mechanic, combustion etc. Basic knowledge about fluid flow is important to understand how to calculate about flow,level and pressure meter. Many people get misunderstand about compressible and incompressible flow for the example. So lets think the basic fluid flow to solve power plant trouble or try to re-design it. Next Internal Incompressible Flow http:/ mechanic-info.blogspot.com/2012/05/internal-incompressible-fluid-flow.html. SI and CI Engine.

Mechanical Engineering: Octane Number
http://mechanic-info.blogspot.com/2011/05/octane-number.html
Machine element, heat transfer, thermodynamic, fluid mechanic, combustion etc. Highest Useful Compression Ratio (HUCR) at which a fuel can be used without detonation in a specified test engine under specified operating condition and the ignition and mixture strength being adjusted to give best efficiency. These fuels are known as the Primary Reference Fuels (PRF) and the octane number of unknown fuel is defined as the percent-age of iso-octane in Primary Reference Fuel that gives the same knock intensity...

Mechanical Engineering: Antifriction Bearing
http://mechanic-info.blogspot.com/2012/09/antifriction-bearing.html
Machine element, heat transfer, thermodynamic, fluid mechanic, combustion etc. The advent of automobile, high speed engines and automatic production machinery provided the impetus for extensive research and development of the rolling bearing (also called the antifriction bearing). Advantage of rolling bearing compared to journal bearing. 1Starting friction torque is low (not much greater than the running frictional torque). 3Less axial space for a comparable shaft diameter. 3 Noisier in normal operation.

Mechanical Engineering: Alimak Elevators
http://mechanic-info.blogspot.com/2014/01/alimak-elevators.html
Machine element, heat transfer, thermodynamic, fluid mechanic, combustion etc. Two Alimak rack and pinion elevators were installed on transmission towers along the Amazon River. With each tower as tall as the Eiffel tower, the Alimak elevators provide access for critical servicing and maintenance. Tallest in South America. At heights of 295m, the transmission towers are the tallest of their kind in South America. With three 500kV power lines and two 230kV lines, the power line systems stretches 1,240...

Mechanical Engineering: SI and CI Engine
http://mechanic-info.blogspot.com/2011/05/si-and-ci-engine.html
Machine element, heat transfer, thermodynamic, fluid mechanic, combustion etc. SI and CI Engine. Table beside is describe comparison between Spark Ignition (SI) and Compression (CI) engine. Otto cycle is more efficient at a given compression ratio and heat input. CI engine has higher thermal efficiency due to higher of compression ratio so that CI engine is heavily built. Exhaust gas temperature for SI engine is high due to low thermal efficiency. Spark Plug Ignition Stroke. July 12, 2013 at 5:48 AM.
